On EPC score it ranks last in the building (50 versus a best of 83). The latest certificate (December 2023) shows an E (score 50), well below the UK norm with real room to improve. Earlier certificates rated it C (January 2011); the latest reading is 2 bands lower.

Today's modelled estimate of £492,000 is 10.1% below the 2007 sale of £547,500, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£925/sq ft) was about 233.4% above the typical sold price in the postcode. Held since September 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 55 m² it's 23.6% smaller than the typical home in the postcode (72 m² median across 9 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs).
